By Kalyan Sundhar – The standards that dictate how 5G systems should work and interoperate were released earlier this year from the Internet Engineering Task Force (IETF) in an eagerly awaited update. The new telecommunications standards cleared the way for those planning to develop, build, or leverage 5G technology.
It is clear that a great deal of thought went into the development of the latest versions of the 5G standards to spur the growth of the 5G market and deliver new opportunities. Technology that follows these standards will ensure that the reliability of these networks is much more stable as it fills in the new market gaps.
This new version of the standards has opened the door for stand-alone (SA) 5G networks that do not rely on 4G for 5G signaling and kicking off a frantic rush to own the 5G market. While 4G networks are still available for added support, companies that do not have an existing 4G infrastructure can build their 5G deployments from scratch. This is due to a section of the standards that governs 4G handovers through interweaving 5G cells with existing 4G deployments.
The standards are only the foundation that will support the development of the 5G industry, but there is still plenty of work needed by companies to get it right. What that will look like is up to individual interpretation as there are gaps in the guidelines that make up the new standards. Interoperability will continue to be a challenge as organizations implement proprietary visions for 5G within those gaps. more>

5 key wireline network improvements needed for 5G
By Brian Lavallee – Ask an end-user about how their phone connects to the network, and they’ll likely only talk about cellular or wireless technology, which is also where most of the current 5G industry hype is focused, and for good reason, as this is the first part of the network to be upgraded. However, the reality is that RAN (Radio Access Network) only makes up a small portion of the end-to-end path that data from a connected device must travel to provide connectivity. The rest of the path is primarily a fiber-optic transport network.
With 5G coming soon, featuring data rates as much as 100 times faster than what’s currently available, the wireline infrastructure that connects end-users (man and machine) to accessed content residing in data centers, must be ready to support upwards of 1,000 times more data flowing across it.
How can network operators prepare? Well, here are five key areas within the wireline network that will need to be upgraded and modernized to support 5G.
- Network Slicing
The move to 5G won’t be a simple network upgrade. It’s a long journey with a high-performance wireline network as the critical component to commercial success for both 4G strategies and the evolution toward 5G. more>

By Nitin Dahad – A manufacturer of III-V photonic devices claims to have proven the feasibility of 60-GHz radio over fiber (ROF) transmission at a 1,270-nm wavelength, paving the way to potential solutions for 5G networks.
CST Global, a Scotland-based subsidiary of Sivers IMA Holdings AB in Kista, Sweden, carried out the feasibility study as part of an EU Horizon 2020 research project. The project, iBROW (innovative ultra-broadband ubiquitous wireless communications through tera-hertz transceivers), was led by the University of Glasgow and managed within CST Global by research engineer Horacio Cantu.
The company says that ROF networks are emerging as a completely new and promising communication paradigm for delivering broadband wireless access services and fronthaul at 60 GHz, relying on the synergy between fixed optical and millimeter-wave technologies. ROF technology enables RF signals to be transported over fiber across kilometers and can be engineered for unity gain RF links. Hence, it is thought that it could do a lot to ease spectrum constraints, and it can replace multiple coax cables with a single fiber-optic cable. Among several benefits, ROF could also enhance cell coverage. more>

Future of 5G
By Susan Friedman, Brian Lavallée – 5G is coming, and with it comes the expectation of wireless speeds that are 100X or more what we experience today with 4G. In fact, one of the goals of 5G is to achieve maximum download speeds of 10 Gbps per user. This influx of traffic won’t come without a cost to the underlying networks that support it.
To succeed, mobile network operators (MNOs) will need more than just a new radio access network, they will also need fiber—and lots of it – to manage the massive increase in bandwidth that will come as billions more users, both human and machine, join the network.
5G is expected to be deployed strategically in different locations, especially in the early days. If consumers are expecting all 3G and 4G networks to be replaced with 5G, they’ll be disappointed. 5G is expected to complement 3G/4G where it makes sense. And depending on where service providers believe applications and use cases will be most lucrative, they can roll out speeds of up to 10 Gb/s.
This means if you’re in a rural community, chances are you probably won’t get 5G in the early days. In cities and metro areas you’ll see potential applications like enhanced mobile broadband, self-driving cars, video broadcast services, and other use cases that will require high-bandwidth and/or low-latency. So, service providers will deploy 5G in geographic areas where it makes economic sense. more> https://goo.gl/kmxQSs

By Gino Skulick – While most in the mobile industry agree that bigger data, richer content and the promise of 5G is transforming the mobile experience, many handset manufacturers and ecosystem players may not fully understand what is required in hardware and software to take full advantage of this transformation.
Today’s mobile devices are not equipped to handle the upcoming barrage of memory and storage requirements that the next-generation of high-bandwidth multimedia and video will demand.
For example, in the existing 4G/LTE environment, most users wouldn’t even consider streaming UHD content or attempt to share their immersive gaming session. However, with 5G’s promise of 3.6Gbps data speeds, these richer multimedia experiences become a reality. What users may not realize is that when streaming content, their mobile device is actually performing file caching” in the background, temporarily buffering the video and reading/writing into memory.
This scenario requires both increased memory size and improved storage performance; the device’s memory subsystem must have the ability to read and write as fast as the network, otherwise a performance bottleneck is created. more> http://goo.gl/DjleXd
